This weeks is to be viewed as a bit of a comic strip.
Effect and Cause, Cause and Effect.

What ever is causing such a contemplating look?

Why it is his recent test of his Game of Life program.

Hacklab the choose your own adventure?

Hacklab the movie Exclusive still preview.

Todays post was originally suppose to be a comic strip that ended upon a past internet Meme which has recently been gracing the lab, specifically the LED sign.                                                               The Meme in question is the video of Rick Astley – Never Gonna Give You Up.  The LED sign just cant handle the current video this internet favourite, but I have high hopes for the video/animation currently in use with some more tweaking and editing it could be fully working in no time.                                         So instead of my intended comic I am present everyone with a mashup between a make your own caption, and what I am calling Hacklab the movie.

LED Sign Hacking

Led Sign Block Diagram
We’ve started a Hacklab project to bring utility to some surplus LED sign panels that have been hanging around the HackLab! These panels use a high-speed digital serial interface, which has been reverse-engineered by Dan and Andrew. It’s a very complicated and strange system. If you’re interested in digital logic, ask us to explain how it works.

In order to make the panels easy to use for members, we’re going to permanantly mount them on the wall over the stairs.  They’re going to be attached to a nice painted piece of plywood (steev!) and wired up to a server.  We’re going to do some circuitry to allow the sign’s power to be automatically controlled.

We’re going to interface the LED panels with a host computer using an Arduino.  Our previous efforts pushed the limits of the Arduino’s performance, but we were running completely unoptmized code.  Hopefully with a few tweaks, and by getting a bit more low level, we can move the serial data fast enough for an adquite scan rate.

The Arduino’s USB Serial interface will be used to interface the sign with the host computer, which will most likely be running BMix with a custom output plugin.  BMix is software developed by Andrew, Dan and Jonathan for the Blinkenlights project in Toronto, and is very good at controlling a matrix of lights.  It will allow the display to be operated using a standard UDP protocol which already has lots of language support, and will also allow it to be easily shared between a number of users and applications at the lab.  There’s even a video game API.

This is the start of the project and the basic design… More information, photographs, and geeky details will be coming as we dig deeper.
